Description

Hey,
I'm trying to integrate https://symfony.com/doc/current/form/dynamic_form_modification.html into EasyAdminBundle but honestly it's a bit frustrating.

The code itself works well enough BUT since you have to recreate the choice field every time it seems to loose its attributes set by EasyAdmin.

What would be A LOT! easier would be the ability to overwrite just the choices using the Form events, so the elements keep the rest of their configuration.

Example

Could be as simple as something like that:

$event->getForm()->get('someChoice')->replaceChoices([
  "new choice" => "nice"
])
